The EU adopted a definition of a nanomaterial in 2011 - Recommendation on the definition of a nanomaterial 2011/696/EU).

A natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm - 100 nm.
In specific cases and where warranted by concerns for the environment, health, safety or competitiveness the number size distribution threshold of 50 % may be replaced by a threshold between 1 and 50 %.
The Recommendation 2011 applies to “natural, incidental or manufactured” nanomaterials as below described:

  • Natural materials occur in the environment without human intervention, as for example volcanic ashes, clay minerals
  • Incidental means materials resulting from a human-induced process with a purpose other than producing nanomaterials, as for example combustion processes
  • Manufactured materials usually refer to materials made for a specific purpose

Nanomaterials and sustainable innovation
The identification, characterization and quantification of nanomaterials in industrial processes, products and biological media is essential for the protection of environment and human health, as well as crucial to innovate in a responsible and sustainable production, and in the product life cycle.


Our multi-technique approach for the detection and characterisation of nanomaterials:

  1. Qualitative screening
  2. Size distribution and morphology
  3. Surface area (optional)
  4. Chemical Identification
  5. Quantification
  6. Risk assessment (if needed)
